The Suling is a simple bamboo flute. A notch is cut into the the side of the top
end, and this top end is surrounded by a rattan of bamboo ring, leaving a small slit where
the player will put his mouth on. Suling is the simplest and cheapest instrument in
the gamelan.

There are basically two types of Sulings. A five finger-holes and a four
finger-holes. Each for a different tuning system. Five finger-holes for pelog
system and four for slendro system.

With its different color of sound, it provides one of the most expressive lines in the
ensemble. It sometimes grouped with the Rebab and the voice, but its part is freer.
Compared to other counter-melody instruments, its musical phrases is shorter and
disjointed, rather than as a continuous line.
